Abstract: To date there is an inadequate information about the analytical model of wave energy converter based on water mass gravity force to generate clean energy. This work proposed an analytical model of wave energy converter based on that previously studied using physical model that were carried out in laboratory experiment at Hasanuddin University Indonesia. This model was derived from analytical of regular wave and converter interactions. Moreover, the proposed analytical model was validated by comparing the simulation result with the previous physical model laboratory experimental result. Analytical model simulation and physical model experiment results, showed a similar trend under wave height and period variation respectively, despite the fact that there were slightly different Power Take Off value. Furthermore, this proposed analytical model will be very useful in predicting the magnitude of electricity that can be generated by means of wave energy converter based on water mass gravity force. The analytical model indicated that the converter’s Power Take Off do not depend entirely on the wave height and period. However, the amount of generated power needed can be achieved by varying the number and volume of gravity weights respectively.
